FLUID TYPE
Use SAE 80W-90 or SAE 90W hypoid gear lubricant with MIL-L-
2105-C and API GL-5 ratings. Also add a container of Mopar Gear Oil
Friction Modifier when refilling.
FLUID DRAIN & REFILL
1) With lubricant of rear axle assembly at operating
temperature, raise and support vehicle so rear wheels are free to
rotate. Clean around axle housing cover. Loosen axle housing cover
bolts. Drain lubricant from axle housing. Remove bolts and axle
housing cover.
2) Position differential so hole in differential case is
facing downward. Wipe out all accessible areas of axle housing. Ensure
sealing surfaces on axle housing and cover are clean. Apply a 1/4"
thick bead of silicone sealant on inside of bolt holes and along
sealing surfaces on axle housing cover.
3) Install axle housing cover, axle identification tag and
retaining bolts. Tighten bolts to 30-35 ft. lbs. (41-47 N.m). Remove
oil filler plug. Add a container of Mopar Gear Oil Friction Modifier.
Fill axle with gear lube. Install oil filler plug. Lower vehicle.
TROUBLE SHOOTING
DIFFERENTIAL NOISE
1) Ensure differential lubricant is at normal operating
temperature. Road test vehicle. Note if differential noise exists in
turns, but not during straight-ahead driving. Probable cause is
incorrect or insufficient rear axle lubricant or additive.
2) Drain and refill rear axle. See FLUID DRAIN & REFILL under
LUBRICATION. Road test vehicle making 10-12 slow figure-8 turns and
note if noise still exists. It may be necessary to disassemble rear
axle so differential can be repaired. See RBI FULL FLOATING AXLES
article for removal of differential case.

TIMING CHAIN
Inspection
1) Remove front cover. See FRONT COVER. Position ruler at
camshaft sprocket, near timing chain link, to check timing chain
stretch.
NOTE: When applying torque to camshaft sprocket bolt, DO NOT allow
crankshaft to move. It may be necessary to hold crankshaft.
2) Place torque wrench on camshaft sprocket bolt. Apply 30
ft. lbs. (41 N.m) torque with cylinder heads installed, or 15 ft. lbs.\
(20 N.m) with cylinder heads removed, on camshaft sprocket bolt in
direction of engine rotation. Note reading on ruler.
3) Apply same amount of torque in opposite direction and note
amount of timing chain movement on ruler. If movement exceeds 1/8" (3.
17 mm), replace timing chain.
Removal
Rotate crankshaft so timing marks are aligned. See Fig. 8.
Remove camshaft sprocket bolt, camshaft sprocket, timing chain and
crankshaft sprocket.
Installation

are aligned. See Fig. 8. Install camshaft sprocket bolt and tighten to
specification. See TORQUE SPECIFICATIONS table.
2) Ensure camshaft end play is within specification. See
CAMSHAFT table under ENGINE SPECIFICATIONS. If end play is not within
specification, replace thrust plate located between camshaft sprocket

CAUTION: After removing fan clutch assembly, DO NOT store fan clutch
with rear of shaft pointing downward. Silicone fluid from fan
clutch may drain into fan drive bearing, causing lubricant
failure.
Removal

fan clutch assembly as a unit. Locate accessory drive belt tensioner,
and rotate tensioner clockwise (counterclockwise on heavy-duty cycle
engines) to release tension on accessory drive belt.
4) Note drive belt routing for installation reference. Belt
must be correctly routed during installation, or engine will overheat
due to water pump rotating in wrong direction.
5) Remove bolts and water pump pulley. Disconnect lower
radiator hose and heater hoses. Remove coolant return tube from water
pump. Remove bolts, water pump and gasket.
Installation
To install, reverse removal procedure using NEW gasket.
Tighten bolts to specification. See TORQUE SPECIFICATIONS table. Fill
